DIVING-DRESS.

SPECIFICATION forming part of Letters Patent No. 462,202, dated October 27, 1891. Application filed October 31, 1890. Serial No. 369,999. (No model.) Patented in England February 26, 1890,15). 3,083.

To to whom it may concern/.-

lie it known that I, WILLIAM CAREY, G. 15., colonel Royal Artillery, a subject of the Queen of Great Britain, and a resident of Southampton, England, have invented certain new and useful Improvements in DivingDresses, (for which I have obtained a patent in Great Britain, No. 3,083, dated February 26, 1800,) of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to diving-dresses, and is designed to improve the construction and increase the efficiency of the same.

Heretofore diving-dresses have usually been constructed in such a manner that when the diver is in the dress one or more additional weights are required to cause him to sink in the water. Moreover, such dresses have ordinarily been so made that the pressure of air within the diving-dress has had to be maintained equal to that of the water on the exterior of the dress, Consequently with the diving-dresses hitherto constructed the diver himself when Working at great depths is subjected to very heavy pressure, the dress affording no protection to him in this respect, and the divers movements in the water are greatly impeded by his dress and by the ad ditional weight or weights used for causing the dress with the diver therein to descend in the water.

My present invention is designed to facilitate the carrying out of submarine operationsthat is to say, to enable divers to work with safety at greater depths and for longer periods than has hitherto been practicable, and to move in the water with greater ease and comfort than heretofore. For this purpose 1 construct my improved diving-dress on the same principles as those on which the shell-of the lobster or crab is formed. In other words, I so construct the diving'dress that the weight thereof with the diver in it will be equal or approximately equal to the weight of the water displaced thereby. Therefore my improved diving-dress, though sufficiently buoyant to float by itself on the surface of the water, will when the diver is in the dress be caused by his weight, in addition to its own, to sinkin the water, provided the diver-remains motionless. The diver can,

however, by moving his limbs as required, rise in the water or travel through the same in any desired direction, the weight of the li nib-casings being so proportioned that when either limb is raised by muscular action, the correspondinglinib-casing will rise by its own buoyancy. Moreover, I so construct my improved diving-dress that it will withstand very high external pressure, thus obviating the necessity for introducing air under similar pressure into the dress. The pressure of the water is therefore borne not by the body of the diver, but entirely by the dress itself.

My diving-dress is made with peculiarlyconstructed spherical joints, whereby the separate parts of the dress are united in such a manner that the diver can freely use his limbs, and which are so constructed that the outer spheres of the said joints, which are formed in separate halves or parts, will be firmly closed and held together by the external pressure of the water, and very light clasps or fastenings of any convenient shape or form will serve for retaining them in place when the diver is out of the water. Each of these spherical joints is so constructed and arranged that its axis or center is coincident or approximately coincident with the joint of the divers body to which it corresponds.

Another feature of my said invention is the construction of the diving-dress in such a manner that the head-piece or helmet and the trunk or body portion extending to the stomach of the diver are or may be formed in a single piece, whereby a considerable increase in capacity is secured, and a storage of air is obtained sufficient to enable the diver to breathe for a considerable time in the event of injury to the air-tubes.

Another feature of my said invention is the arrangement of the inner spherical portion of the joint to work on pivots formed upon the interior of the outer spherical portion thereof, thus obviating the mechanical difficulties arising from the introduction of such pivots from the outside through a pivothole and the consequent liability to leakage and other defects.

My improved divingdress may be constructed of aluminium, bronze, or other suitable metal or material of sufficient strength to resist the pressure of the water to which
